asset_field_not_list
The value of the 'assets' field is expected to be a list of relative file paths.
Description
#The analyzer produces this diagnostic when the value of the assets
key isn't a list.
Example
#The following code produces this diagnostic because the value of the assets
key is a string when a list is expected:
yaml
name: example
flutter:
assets: assets/
Common fixes
#Change the value of the asset list so that it's a list:
yaml
name: example
flutter:
assets:
- assets/
